Raffertys restaurant - Offensive wait staff

Dining at the Lexington location (not the one on hamburg) my waiter used the word "retard" twice, complained the kitchen staff were idiots and cussed while he spoke with us.I enjoy the facility and food but staff like that really brings the business down.

I did refuse to tip him in honor of my special needs son. I remember his name was Alex S on the receipt. I'm highly upset and really don't plan on returning due to the fact of possibly having the same server. Please have some sensitivity training with your staff.
